from the overflow of sewers and fertilized fields. A higher frequency in storms cause much more stagnant water to occur‚ which can result in an increased mosquito population‚ and the increased risk of epidemic to arise. Not only does stagnant water increase the mosquito population‚ but slight increases in climate temperatures can increase the mosquito population by greatly.

Here‚ we describe and compare most of the common technologies used for magnetic field sensing. These include search coil‚ fluxgate‚ optically pumped‚ nuclear precession‚ SQUID‚ Hall-effect‚ anisotropic magnetoresistance‚ giant magnetoresistance‚ magnetic tunnel junctions‚ giant magnetoimpedance‚ magnetostrictive/piezoelectric composites‚ magnetodiode‚ magnetotransistor

114 Faraday’s Law of Induction Stephanie Scott Section: 10849 Group #3 Bochao Li 3/31/15 Abstract: The objective of the Faraday’s Law of Induction lab was to verify Faraday’s law of induction by measuring the emf generated in a small coil and comparing it with the calculated value. Secondly the goal was to investigate the relationship between the emf and the frequency of the driving signal. The magnetic field was found to be uniform throughout. For the frequency of 40 Hz‚ the average

Malaria in Africa Malaria has been known to exist for thousands of years‚ with its signs documented as early as 5000 years ago in ancient Chinese and Egyptian records. Through out these thousands of years‚ it is believed that this disease has evolved and adapted to its surroundings. Malaria is a parasitic disease in the blood that causes flu-like symptoms. Some signs of this disease include fever‚ chills‚ muscle pain‚ headache‚ nausea‚ vomiting‚ and may also cause jaundice and other serious complications

Malaria in Tanzania effects it’s country economically‚ socially and environmentally‚ but by taking the right steps‚ Malaria can be cured. Malaria is a widespread disease in Africa that is transmitted by the bite of a female mosquito. Malaria impacts a human physically‚ mentally and emotionally. Symptoms include a headache‚ fever‚ fatigue‚ dry cough‚ spleen enlargement and continuous vomiting. In Tanzania‚ approximately 93.7 out of 1000 people die of Malaria each year.
